I've just released a new 'Lesson Objectives' block for Moodle, that allows you to display the objectives for the current lesson in the side bar (you can enter a timetable, linked to groups, so it knows which list of objectives to display to each student).
You can also enlarge the objectives list, to show from the front of a class and tick-off each objective as it is completed in the lesson. Students can click on a link to view all the objectives, one week at a time, in order to review the lesson progression.
You can also find it on GitHub here: https://github.com/davosmith/moodle-objectives (which is useful if the modules & plugins entry is ever awaiting re-approval, after an update).
Please let me know of any problems or suggestions for improvement.
